Specification of Letters Patent.

Patented Dec. 31, 1907.

Application filed August 3, 1907. Serial No. 386,971.

v T all whom it may concern:

Be it known that I, FRANK 0. BROWN, a citizen of the United States,residing at Asherville, in the county of Mitchell and State of Kansas,have invented certain new and useful Improvements in Lawn-Shears, ofwhich the following is a specification. 1

This invention provides an implement of novel form to admit of trimmingthe grass on lawns close to fences, sidewalks, trees, plants andshubbery.

In its construction, the implement resembles a pair of shears having ahandle, a pair of blades and operating means, the latter being of suchformation as to enable the implement to be manipulated and worked by onehand.

For a full understanding of the invention and the merits thereof andalso to acquire a knowledge of the details of construction and the meansfor effecting the result, reference is to be had to the followingdescription and accompanying drawings.

While the invention may be adapted to different forms and conditions bychanges in the structure and minor details without departing from thespirit or essential features thereof, still the preferred embodiment isshown in the accompanying drawings, in which:

Figure 1 is a perspective view of lawn shears embodying'the invention.Fig. 2 is a sectional view on the line 0c0c of Fig. 1. Fig. 3 is adetail view of the base receiving the stationary shear blade, but eachblade is relatively adjustable to compensate for wear.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The shears comprise a movable blade 1 and a fixed blade 2, the twoblades being pivoted. at 3 by means of a suitable fastening. The fixedblade 2 is provided with a handle which by preference is of sectionalformation. A base plate 4 forms a support for the fixed blade 2 and thelower portion 5 of the handle projects therefrom and terminates at itsupper or outer end in a socket in which is secured the upper portion 6of the handle. The fixed blade 2 is formed near opposite ends withtransverse'slots 7 through which fastenings 8 pass and serve to securethe blade 2 to the base or support 4 in the adjusted position. WVhilethe blade 2 is adapted to be secured to thebase or support 4 in anadjusted position, it, nevertheless, remains fixed whenin operation andis adjustedpto compensate for wear only.

The movable blade 1 overlaps the. blade 2 and is provided with a curvedarm 9 which serves to impartan oscillatory or piv= i otal movement tothe bla'de l. The arm 9 is fiat and has sliding or running connectionwith one arm of a lever 10pivoted at 11 to the handle. The lever 10crosses the handle and projects from. opposite sides thereof; 1 i

The end of the lever 10 cooperating with the curved arm 9 is slotted toreceive said arm and is provided with pulleys 12 between which thecurved arm 9 is arranged, said pulleys being grooved in their edges toreceive opposite edge portions of the curved arm and prevent frictionalcontact of said arm with the sides of the lever bordering upon the slotthrough which the curved arm 9 passes. As the lever 10 is oscillated, itcooperates with the curved arm 9 and imparts a corresponding movement tothe blade 1, whereby the shears are opened and closed in the well knownmanner. A handle lever 13 pivoted at one end to the handle of theimplement, is connected by means of a rodll with the end of the lever 10opposite to that cooperating with the curved arm 9 and is springactuated to normally hold the shear blades open. The spring 15 exertinga pressure upon the handle lever 13 is interposed between said lever andthe grip 16 at the upper or outer end of the handle.

The shear blades may be of any length and the handle extended therefrommay be straight or of any form best adapted to the convenience of theoperator, so as to obviate bending or stooping when using the implementfor trimming the lawn. The grip 16 and the hand lever 13 are of suchconstruction and relation as to admit of both being conveniently grippedby the hand so that upon tightening the grip, the lever 13 may be movedtowards the grip 16 and thereby operate the'lever 10 to effect closingof the shears. Upon relaxing the grip, the lever 13 moves away from thegrip 16 by the action of the spring 17, thereby automatically openingthe shears. It will thus be understood that the shears are operated byalternately tightening and relaxing the grip upon the parts 13 and 16.As will be obvious, the construction of the implement is such as toadmit of its convenient use close to fences, sidewalks, plants andshrubbery, where the ordinary lawn mower cannot be advantageously used.

Having thus described the invention, what is claimed as new is:

1. In an implement of the character set forth, the combination of ashear blade, a second shear blade having pivotal connection with thefirst mentioned shear blade and provided with a curved arm, an operating lever having a slot to receive the curved arm of the pivoted shearblade, spaced pulleys mounted upon the operating lever and receiving thesaid curved arm between them, and means for imparting oscillatorymovement to the operating lever to effect opening and closing of theshear blade.

2. In combination, a shear blade, a second shear blade having pivotalconnection with the first mentioned shear blade and provided with acurved arm, an operating lever, spaced pulleys mounted upon theoperating lever and receiving the said curved arm be tween them, andmeans for lmparting osc1l- "latory movement to said operating lever.

3. In combination, a relatively fixed shear blade, a handle extendedtherefrom, a pivoted shear blade cooperating with the 'fiXGCl shearblade and having a curved arm,

an operating lever pivoted between its ends to the said handle andhaving an end portion cooperating with the said curved arm to impart anoscillatory movement to the pivoted shear blade, a lever pivoted to saidhandle, and connecting means between the said lever and the operatinglever.

In testimony whereof I afiiX my signature in presence of two witnesses.

FRANK C. BROWN.
